How to use variables in Advertisement?

[dba]

There is a need to use variables in advertising (to pass the subid to the advertising widget). But advertising is displayed "as is" and does not accept variables.
Is there any solution for this issue?

Advertising can use dynamic variables that are passed in URL.

For example if you need to use variable passed like

https://www.domain.com/?adv=555

Then go to Settings -> Website settings and under Dynamic HTTP parameters add this:
adv

and specify its default value (something that should be printed in advertising if no ?adv=555 parameter is passed in URL.

Then in advertising code you can use this:
<ins class="adsbyexoclick" data-zoneid="xxx" data-sub="%adv%"></ins>

If user comes with
https://www.domain.com/?adv=555

then it will be displayed like
<ins class="adsbyexoclick" data-zoneid="xxx" data-sub="555"></ins>

otherwise it will take the default value that you configured.
